I'm trying model a 70S ribosome using pdb files 2J00 and 2J01. I can't get the two subunits combined. Visulaizer crashes whenever I try to cut and paste the 30S piece into the 50S file. In fact, if I just open the 50S pdb file and do a Save as in .msv format, the program crashes.

My computer has Dual 64 2.41 MHz processors, 2 MB RAM, and an ATI FireGL graphics accelrator card running Windows xp pro.

Will it help to put more RAM in the box, or is there a limitation on the file size Visualizer can manage? The pdb file for the 50S subunit is 7.2 Mb.

Thanks,
